摘　　要：采用桩与土共同作用的线性分析方法,首先对单桩承载特性、单桩复合地基承载特性进行了模拟,在此基础上分析了群桩复合地基承载特性,并对复合地基进行了优化设计及经济效益分析。所作的复合地基优化设计通过了试验验证及工程验证。提出的方法可用于其他复合地基承载力的优化设计。The bearing characteristic of a single pile and the bearing characteristic of a composite foundation with a single pile are simulated, and then the bearing characteristic of a composite foundation with grouped piles is analyzed, and a optimized design of a composite foundation and the corresponding economic benefit analysis are carried out in this paper using the linear analysis method with soilpile interaction. The optimized design of a composite foundation is verified by a test and a project. The method put forward here can be used to optimize design of all kinds of composite foundation.
